Answer 2

4^3 = 4*4*4 = 64

8 1/5 - 2 = 6 1/5.

PEMDAS = multiplication first

6 1/5 as an improper fraction = 6*5 = 30+1 = 31/5

31/5 * 64 = 1984/5 = 396.8

Since it's in decimal, change 24 3/5 to a decimal:

24 3/5 as a decimal = 24.6

Add:

396.8 + 24.6 = 421.4

The answer is 421.4. It can also be written as a fraction, which is 421 2/5.

Hope this helped☺☺
